This is a lichen of tree bole mosses and tree bole crevices in humid districts of western Ireland. B. marginatum has a greenish-white, thinly-powdery thallus. Discs (0.3-0.7mm diam.) are brown to black, often with a bluish tinge and with a prominent, raised, non-woolly edge (exciple). The spores are three-septate. In Ireland, there are a few records from the north.
